Constant noise in the head – such as ringing in the ears – rarely indicates a serious health problem, but it sure can be annoying. Here’s how to minimize it.
Tinnitus (pronounced tih-NITE-us or TIN-ih-tus) is sound in the head with no external source. For many, it’s a ringing sound, while for others, it’s whistling, buzzing, chirping, hissing, humming, roaring, or even shrieking. The sound may seem to come from one ear or both, from inside the head, or from a distance. It may be constant or intermittent, steady or pulsating.
Almost everyone has had tinnitus for a short time after being exposed to extremely loud noise. For example, attending a loud concert can trigger short-lived tinnitus. Some medications (especially aspirin and other nonsteroidal anti-inflammatory drugs taken in high doses) can cause tinnitus that goes away when the drug is discontinued.
A more serious problem is chronic tinnitus — symptoms lasting more than six months. As many as 50 to 60 million people in the United States suffer from this condition; it’s especially common in people over age 55 and strongly associated with hearing loss. Many people worry that tinnitus is a sign that they are going deaf or have another serious medical problem, but it rarely is.
Most tinnitus is subjective, meaning that only you can hear the noise. But sometimes it’s objective, meaning that someone else can hear it, too.
For example, if you have a heart murmur, you may hear a whooshing sound with every heartbeat; your clinician can also hear that sound through a stethoscope. Many people can hear their heartbeat — a phenomenon called pulsatile tinnitus — especially as they grow older, because blood flow tends to be more turbulent in arteries whose walls have stiffened with age. Pulsatile tinnitus may be more noticeable at night, when you’re lying in bed, because more blood is reaching your head, and there are fewer external sounds to mask the tinnitus. If you notice any new pulsatile tinnitus, you should consult a clinician, because in rare cases it is a sign of a tumor or blood vessel damage.
The course of chronic tinnitus is unpredictable. Sometimes the symptoms remain the same, and sometimes they get worse. In about 10% of cases, the condition interferes with everyday life so much that professional health is needed.
While there’s no cure for chronic tinnitus, it often becomes less noticeable and more manageable over time. You can help ease the symptoms by educating yourself about the condition — for example, understanding that it’s not dangerous.
